## Description

Gear up for cold-weather work with Midweight Synthetic-Merino Wool Blend Base Layer Pants. Built for performance and comfort, these long john bottoms combine merino wool’s natural warmth and moisture-wicking ability with synthetic fibers for durability and fast drying. Perfect for layering under work pants, overalls, or coveralls, these thermal underwear will keep you warm, dry, and odor-free all day.

Review: Last longer than Merino wool - I recently purchased the Carhartt Men's Force Midweight Synthetic-Wool Blend Base Layer lowers and upper, and I have to say, I’m really impressed with it! After wearing it for about a month, I’m very satisfied with both the quality and comfort. I tested these while hunting and while at work. The blend of synthetic and wool material provides a great balance of warmth and breathability, making it perfect for those cooler days. The fit is spot on, it's snug enough to keep me warm without feeling restrictive, and it holds up really well throughout the day. The fabric is soft against the skin and doesn’t itch like some other wool blends I’ve tried in the past. I also love how moisture-wicking it is. Whether I’m working hard outdoors or just running errands, it keeps me dry and comfortable. Carhartt's reputation for durability definitely holds up with this base layer; it feels built to last. I haven't noticed any pilling or wear even after a month of consistent use, which is a huge plus. I’m looking forward to seeing how it holds up over the long term, but so far, it's been an excellent purchase. Highly recommend it for anyone looking for a high-quality, comfortable base layer that can handle whatever you throw at it.
Review: Works great! - I got this product because I am constantly outside for work in the winter. I have had it for 3 years and it still feels comfortable, doesn’t have any holes so it’s durable. It functions great in keeping me warm, but is breathable enough when moving around to not get too how. I have worn it under my putter coat when offshore fishing during the winter as well as kept me warm while up in the mountains material is great, durable, and thick enough to keep warm but thin enough to not overheat. Glad I spent the money on this and looks good too!

### ⭐⭐⭐⭐⭐ It's a gift
*by B***S on November 30, 2024*

And it's a gift worth giving, as Carhartt makes a good product on everything. He wears Carhartt everything as it's his 'go to.' While there are less expensive long underwear for base layers, the fact that Carhartt has 19% wool in them is what sold me. There is nothing at all like wool to retain heat - no fancy "fabrics" of any sort - and that these are also washable/dryable is amazing. He will be happy I am sure.
